TESCOM™ 44-6800 Series Vaporizing RegulatorBoost the reliability of your sample conditioning system with superior sample quality.

Achieve accurate analytical results by preserving the composition of your sample.

1

Your online gas chromatograph analyzer system faces several obstacles that diminish the accuracy of its analysis.

Are your analytical results representative of what’s flowing through your pipes? If not, chances are your sample conditioning system is not delivering the single-phase vapor samples that are required for proper analysis. Lacking accurate and reliable measurements can make it difficult to assess the health of your process and create corrective action plans to minimize the financial impact of any off-specification product. To guarantee the performance of your analyzer, you must take steps to ensure the best sample quality—every time.

“Greater than 70% of the issues experienced in online gas chromatography analysis are caused by unreliable sample conditioning systems.”

– Major Gas Chromatograph (GC) Manufacturer

“I need to be able to trust my analytical results when I’m troubleshooting my unit so I know which operating variables I need to adjust.”

– Refinery Process Engineer

“Excessive repairs and product replacements of faulty components increase my maintenance costs.”

– Petrochemical Plant Manager
